Well, that kinda misses my point.
First "NCAA" isn't a "sport"; it is a number of sports, some of which are holding championships tomorrow, and next week, and ...
Second, of all those other organizations, none I am aware of has yet called off a national championship. Individual conferences have cancelled their conference championships, and professional sports have 'suspended', but not cancelled their season or championship, etc.
I'm keeping my eye on NCAA wrestling, next weekend - the same weekend as women's hockey national championship. If there is any sport being considered here where one's "personal space" becomes an issue. it's gotta be wrestling.
